We present an L2-orthonormal polynomial basis for triangles containing 10 degree polynomials in its span. The sixty-six basis functions are defined by using 35 generating functions {Bk(x, y)} with the property that Bk(x, y) is orthogonal to Bk(y, x) unless they are equal. For tetrahedra, we describe methods for constructing a an L2-orthonormal basis by… (More)
